So why's half of your previous comment about the necessary investment and whales on steem?
It depends on each individual investors risk profile and future expectations what to invest in. And putting all your eggs into one basket is generally not a good idea. If you think the upside potential of real estate is higher than steem's, or if you are shy of the risk steem naturally includes, that's up to you. Speaking of a "best" seems weird.
The good property manager to make it passive cuts even deeper into your profits. Getting half the APR you get here would be exceptional, not considering asset value. The risk is lower, but that's the only thing "better" about it.
